How big is a domestic rabbit brain?
The domestic rabbits were approximately fourfold heavier than the wild rabbits (x ± SEM = 4.12 ± 0.25 kg and 1.07 ± 0.04 kg, respectively), yet had only a slightly larger absolute brain size (total brain volume, 9.55 ± 0.35 mL vs. 7.98 ± 0.26 mL) (Fig. 1A).
Do rabbits have big brains?
“Firstly, wild rabbits have a larger brain-to-body size ratio than domestic rabbits. Secondly, domestic rabbits have a reduced amygdala and an enlarged medial prefrontal cortex. Thirdly, we noticed a generalized reduction in white matter structure in domestic rabbits.”
